1971 plymouth duster parts car

Ive got a 71 duster parts car. Rust has eaten the unibody and floor. The rails and floor are shot. Some of the firewall around the pedals, steering stem area, trunk floor, and inner fender wall, driver side rear quarter around wheel well. Looking from the outside you would think its a decent car.

Im buying another duster and will swap a couple parts from the cars. I really want to sell the car whole. It is located in southern vermont. I would like $1250 or best offer for the car. Ive seen worse asking for more.
